He was detained in north Belfast on Tuesday morning as part of the renewed investigation into the case and was released later that day.
Mr Tang, 28, died after he was attacked and robbed outside his takeaway business in June 1996.
His watch and the night's taking were stolen during the attack. He was taken to hospital but died from his injuries.
No-one has been convicted of his murder.
Five people, three men and two women, have been charged with offences linked to the murder in the past number of months.
